Before anything, if you have not watched the sitcom, maybe watch it first before playing this, as I felt players will get the jokes more, or appreciate some of the scenes more, if they have watched the show.
That being said, in the game, players need to earn more cash. Earning is pretty much automated, and earning more cash will allow players to unlock more desks, and unlocking desks will hire more workers. Players can also upgrade their characters, making them look better... and earn more cash. And to upgrade the characters, players would need to spend a very valuable resource... coffee. This is pretty much an idle game with The Office characters.
Overall, it's a fun idle game, and I appreciated it more as I have already watched the entire series. Pretty much a must for any Office fan.
